Abstract
BACKGROUND The Post-ureteroscopic Lesion Scale (PULS) was designed as a standardized classification system for ureteral lesions after uretero(reno)scopy (URS). This study evaluates its routine use and a possible clinical impact based on a representative patient cohort. MATERIALS AND METHODS Data of 307 patients in 14 German centers within the BUSTER project were used to test 3 hypotheses (H): PULS score shows a high interrater reliability (IRR) after independent assessment by urologic surgeon and assistance personnel (H1); PULS score is correlated with the frequency of postoperative complications during hospital stay (H2); post-URS stenting of the ureter is associated with higher PULS scores (H3). RESULTS Median age of patients was 54.4 years (interquartile range [IQR] 44.4-65.8; 65.5% male). Median diameter of index stones was 6 mm (IQR 4-8) with 117 (38.4%) pyelo-caliceal and 188 (61.6%) ureteral stones. Overall, 70 and 82.4% of patients had pre-stenting and post-URS stenting, respectively. Stone-free status was achieved in 68.7% after one URS procedure with a complication rate of 10.8% (mostly grade 1-2 according to Clavien-Dindo). PULS scores 0, 1, 2 and 3 were assessed in 40%, 52.1%, 6.9% and 1% of patients, respectively, when estimated by urologic surgeons. PULS score showed a high IRR between the urologic surgeon and assistance personnel (κ = 0.883, p < 0.001), but was not significantly correlated with complications (ρ = 0.09, p = 0.881). In contrast, a significant positive correlation was found between PULS score and post-URS stenting (ρ = 0.287, p < 0.001). A PULS score of 1 multiplied the likelihood of post-URS stenting by 3.24 (95% confidence interval 1.43-7.34; p = 0.005) as opposed to PULS score 0. CONCLUSIONS Removal of upper urinary tract stones using URS is safe and efficacious. Real-world data provided by this study confirm a high IRR of the PULS score and its clinical impact on the indication for post-URS stenting. A future prospective randomized trial should evaluate a possible standardization of post-URS stenting based on PULS score assessment.

Abstract
Within the BUSTER trial, we analyzed the surgeon's amount of experience and other parameters associated with URS procedures regarding the stone-free rate, complication rate, and operative time. Patient characteristics and surgical details on 307 URS procedures were prospectively documented according to a standardized study protocol at 14 German centers 01-04/2015. Surgeon's experience was correlated to clinical characteristics, and its impact on the stone-free rate, complication rate, and operative time subjected to multivariate analysis. 76 (25%), 66 (21%) and 165 (54%) of 307 URS procedures were carried out by residents, young specialists, and experienced specialists (> 5 years after board certification), respectively. Median stone size was 6 mm, median operative time 35 min. A ureteral stent was placed at the end of 82% of procedures. Stone-free rate and stone-free rate including minimal residual stone fragments (adequate for spontaneous clearance) following URS were 69 and 91%, respectively. No complications were documented during the hospital stays of 89% of patients (Clavien-Dindo grade 0). According to multivariate analysis, experienced specialists achieved a 2.2-fold higher stone-free rate compared to residents (p = 0.038), but used post-URS stenting 2.6-fold more frequently (p = 0.023). Surgeon's experience had no significant impact on the complication rate. We observed no differences in this study's main endpoints, namely the stone-free and complication rates, between residents and young specialists, but experienced specialists' stone-free rate was significantly higher. During this cross-sectional study, 75% of URS procedures were performed by specialists. The experienced specialists' more than two-fold higher stone-free rate compared to residents' justifies ongoing efforts to establish structured URS training programs.

Abstract
Over the past few decades, some principles in the treatment of penile cancer have changed fundamentally. While 15 years ago a negative surgical margin of at least 2 cm was considered mandatory, organ-sparing surgery permitting minimal negative surgical margins has a high priority nowadays. The current treatment principle requires as much organ preservation as possible and as much radicality as necessary. The implementation of organ-sparing and reconstructive surgical techniques has improved the quality of life of surviving patients. However, oncological and functional outcomes are still unsatisfactory. Alongside with adequate local treatment of the primary tumour, a consistent management of inguinal lymph nodes is of fundamental prognostic significance. In particular, clinically inconspicuous inguinal lymph nodes staged T1b and upwards need a surgical approach. Sentinel node biopsy, minimally-invasive surgical techniques and modified inguinal lymphadenectomy have reduced morbidity compared to conventional inguinal lymph node dissection. Multimodal treatment with surgery and chemotherapy is required in all patients with lymph node-positive disease; neoadjuvant chemotherapy has been established for patients with locally advanced lymph node disease, and adjuvant treatment after radical inguinal lymphadenectomy for lymph node-positive disease. An increasing understanding of the underlying tumour biology, in particular the role of the human papilloma virus (HPV) and epidermal growth factor receptor (EGFR) status, has led to a new pathological classification and may further enhance treatment options. This review summarises current aspects in the therapeutic management of penile cancer.

Abstract
BACKGROUND Due to increasing antibiotic resistances, relevant treatment problems are currently emerging in clinical practice. In March 2015, the German Federal Ministry of Health (BMG) published a 10-point plan designed to combat this development. Furthermore, the first German guideline on antibiotic stewardship (ABS) was implemented in 2013 and instructs physicians of different specialties about several treatment considerations. Evidence is scarce on how such concepts (10-point plan/BMG, ABS) are perceived among clinicians. MATERIALS AND METHODS Within the MR2 study (Multiinstitutional Reconnaissance of practice with MultiResistant bacteria - a survey focusing on German hospitals), a questionnaire including 4 + 35 items was sent to 18 German hospitals between August and October 2015, surveying internists, gynecologists, general surgeons, and urologists. Using multivariate logistic regression models (MLRM), the impact of medical specialty and further criteria on the endpoints (1) awareness of the 10-point plan/BMG and (2) knowledge of ABS measures were assessed. Fulfillment of endpoints was predefined when average or full knowledge was reported (reference: poor to no knowledge). RESULTS Overall response rate was 43% (456/1061) for fully evaluable questionnaires. Only 63.0 and 53.6% of urologists and nonurologists (internists, gynecologists, and general surgeons), respectively, attended training courses regarding multidrug-resistance or antibiotic prescribing in the 12 months prior to the study (P = 0.045). The endpoints average and full knowledge regarding 10-point plan/BMG and ABS measures were fulfilled in only 31.4 and 32.8%, respectively. In MLRM, clinicians with at least one previous training course (reference: no training course) were 2.5- and 3.8-fold more likely to meet respective endpoint criteria (all P < 0.001). Medical specialty (urologists vs. nonurologists) did not significantly impact the endpoints in both MLRM. CONCLUSIONS The 10-point plan/BMG and ABS programs should be implemented into clinical practice, but awareness and knowledge of both is insufficient. Thus, it stands to reason that the actual realization of such measures is inadequate and continuous training towards rational prescription of antibiotics is necessary, regardless of medical specialty.

Abstract
OBJECTIVE Measurement of prostate-specific antigen (PSA) is not only used as a screening instrument by urologists, but also by general practitioners and internal specialists (GP-IS). Until now, there are neither data on the approach of German GP-IS in practicing this nor have data been classified in the context of available international literature on this topic. MATERIALS AND METHODS Between May and December 2012, a questionnaire containing 16 items was sent to 600 GP-IS in Brandenburg and Berlin. The response rate was 65% (392/600). Six indicator questions (IQ1-6) were selected and results were set in the context of available international data. The quality of present studies was evaluated by the Harden criteria. RESULTS Of the 392 responding physicians, 317 (81%) declared that they would use PSA testing for early detection of PCA (IQ1) and, thus, formed the study group. Of these GP-IS, 38% consider an age between 41 and 50 years as suitable for testing begin (IQ2), while 53% and 14% of the GP-IS perform early detection until the age of 80 and 90 years, respectively (IQ3). A rigid PSA cut-off of 4 ng/ml is considered to be reasonable by 47% of the involved GP-IS, whereas 16% prefer an age-adjusted PSA cut-off (IQ4). Patients with pathological PSA levels were immediately referred to a board-certified urologist by 69% of the GP-IS. On the other hand, 10% first would independently control elevated PSA levels themselves after 3-12 months (IQ5). Furthermore, 14% of the interviewed physicians consider a decrease of PCA-specific mortality by PSA screening as being proven (IQ6). Knowledge regarding PCA diagnostics is mainly based on continuous medical education for GP-IS (33%), personal contact with urologists (6%), and guideline studies (4%). While 53% indicated more than one education source, 4% did not obtain any PCA-specific training. The results provided by this questionnaire evaluating response of German GP-IS to six selected indicator questions fit well into the international context; however, further studies with sufficient methodical quality are required. CONCLUSIONS Despite current findings and controversial recommendations of the two large PCA screening studies on this issue, German GP-IS still frequently use PCA screening by PSA measurement. Primary strategies of early detection as well as follow-up after assessment of pathologically elevated PSA levels poorly follow international recommendations. Thus, an intensification of specific education is justified.

Abstract
BACKGROUND In various studies it has been shown that obesity enhances the risk for a unfavorable pathological tumour stages, higher Gleason scores (GS), positive surgical margins (PSM), and certain perioperative parameters (higher blood loss, higher length of surgery, higher complication rates) after radical prostatectomy. However, for robot-assisted radical prostatectomy (RARP) there are only a few studies addressing this topic with partially conflicting results. Furthermore, none of these studies actually represents the clinical practice pattern as performed in a European centre. MATERIAL AND METHODS Beside further clinical and histopathological parameters, also body mass index (BMI) of patients undergoing RARP was recorded. The following categories were registered: BMI of < 25 kg/m², ≥ 25-29.9 kg/m², and ≥ 30 kg/m² defined as normal weight, overweight, and obesity, respectively. The potential correlation between BMI on the one hand and various criteria of aggressive tumour biology and specific perioperative parameters on the other hand has been examined on univariate and multivariable analyses. RESULTS 22.8% (n=79), 59% (n=204), and 18.2% (n=63) of patients of the study group presented with normal weight, overweight, and obesity, respectively. Based on the results of various multivariable regression models there was no significant influence of obesity on pathological tumour stage, pN category, undifferentiated tumour growth (≥ GS7b), upgrading, or PSM rates. Furthermore, obese patients showed a significantly higher intraoperative blood loss and a higher length of surgery, which, however, did not result in a higher rate of grade 3a/b complications according to Clavien-Dindo classification after 90 days. CONCLUSIONS In the present series of consecutive patients undergoing RARP there was no evidence for a more aggressive tumour biology or a higher complication rate in obese patients.

Abstract
BACKGROUND The standard treatment for the muscle-invasive bladder cancer (MIBC) adheres to the open radical cystectomy (RC), although in the last few years the RC was established in some centres. The MIBC with simultaneous renal pathology (carcinoma, loss of function) can be a reason for an RC in combination with a nephrectomy. In the present paper we give a report about our first 3 patients in whom we combined the robotic RC with a laparoscopic nephrectomy as a minimally invasive treatment. PATIENTS AND METHODS Between January and September 2010 3 male patients (average age 66 years) with MIBC and an associated renal pathology (2×loss of function, 1×upper tract carcinoma) were treated by the simultaneous robot-assisted RC and laparoscopic nephrectomy at our hospital. Clinical and pathological criteria, surgical techniques and preoperative complications were recorded prospectively. Follow-up of the 3 patients continued for at least of 18 months. RESULTS In all 3 cases primarily the kidney was prepared in a transperitoneal-laparoscopic way and clipped by the vessel pedicle, then the robot-assisted RC followed and specimens were removed through a 10-cm median laparotomy. In all cases an ileum conduit was built extracorporally in using this way. The median OP time (including nephrectomy, connection of Da-Vinci, RC with extended lymph node dissection) amounted to 7 h (6.5-7.5 h) in total. The intraoperative blood loss was 330 mL on average. One of our patients showed a grade 2 complication following the Clavien-Dindo classification (1×grade 1, 1×without perioperative complications). On average 32 (22-46) lymph nodes were taken out, whereby all patients showed a pN0 status. The pathological stagings of MIBC were pT3a, pT4a and pT4b. With one patient the cancer of the renal pelvis was limited to the lamina propria, with another patient an incidental prostate cancer was detected. All histopathological findings of the different cancers showed negative surgical margins. The median hospitalisation time was 17 (16-19) days. In an 18- to 26-month follow-up period all patients remained without any further postoperative complications and without a tumour relapse. CONCLUSION In this paper we have described the surgical steps of a small series of simultaneous robot-assisted RC and laparoscopic nephrectomy as a minimally invasive treatment in case of a specific indication. As a result of our report, we show that this surgical technique is possible without essential perioperative morbidity and with satisfying oncological results. Long-term data of our patients and results of any further studies are crucial to evaluate the efficiency of this complex surgical method.

Abstract
PURPOSE The 7th edition of TNM for renal cell carcinoma introduced a subdivision of pT2 tumors at a 10 cm cutoff. In the present multicenter study the influence of tumor size as well as further clinical and histopathological parameters on cancer specific survival in patients with pT2 tumors was evaluated. MATERIALS AND METHODS A total of 670 consecutive patients with pT2 tumors (10.4%) of 6,442 surgically treated patients with all tumor stages were pooled (mean followup 71.4 months). Tumors were reclassified according to the current TNM classification, and subdivided in stages pT2a and pT2b. Cancer specific survival was analyzed using the Kaplan-Meier method, and univariable and multivariable analyses were used to assess the influence of several parameters on survival. RESULTS Tumor size continuously applied and subdivided at 10 cm or alternative cutoffs did not significantly influence cancer specific survival. In addition to N/M stage, Fuhrman grade and collecting system invasion also had an independent influence on survival. Integration of a dichotomous variable subsuming Fuhrman grade and collecting system invasion (grade 3/4 and/or collecting system invasion present vs grade 1/2 and collecting system invasion absent) into multivariate models including established prognostic parameters resulted in improvement of predictive abilities by 11% (HR 2.3, p <0.001) for all pT2 cases and 151% (HR 3.1, p <0.001) for stage pT2N0M0 cases. CONCLUSIONS Tumor size did not have a significant influence on cancer specific survival in pT2 tumors, neither continuously applied nor based on various cutoff values. To enhance prognostic discrimination, multifactorial staging systems including pathological features should be implemented. The prognostic relevance of the variable subsuming Fuhrman grade and collecting system invasion should be considered for future evaluation.

Abstract
BACKGROUND Few and partially contradictory data are available regarding the prognostic signature of downstaging of muscle-invasive clinical tumour stages in patients treated with radical cystectomy. MATERIALS AND METHODS Clinicopathological parameters of 1,643 patients (study group, SG) treated with radical cystectomy due to muscle-invasive urothelial bladder cancer were summarized in a multi-institutional database. Patients of the SG fulfilled the following conditions: clinical tumour stage T2 N0 M0 and no administration of neoadjuvant radiation or chemotherapy. Cancer-specific survival (CSS) rates were calculated referring to pathological tumour stages in cystectomy specimens (<pT2, pT2, >pT2) (mean follow-up: 51 months). Furthermore, a multivariable model integrating clinical information was developed in order to predict the probability of downstaging. RESULTS A total of 173 patients (10.5%) of the SG presented with downstaging in pathological tumour stages (pT0: 4.8%, pTa: 0.4%, pTis: 1.3%, pT1: 4.1%); 12 of these patients had positive lymph nodes (7%, in comparison with 21% pN+ of pT2 tumours and 43% of >pT2 tumours). Patients with tumour stages <pT2, pT2 and >pT2 had CSS rates after 5 years of 89, 69 and 46%, respectively (p<0.001). In a multivariable Cox model the presence of pathological downstaging resulted in a significant reduction of cancer-specific mortality (HR 0.30; 95% CI 0.18-0.50). By logistic regression analysis the date of TURB (benefit for more recent operations) was identified as the only independent predictor for downstaging of muscle-invasive clinical tumour stages. Age, gender, grading and associated Tis in the TURB did not reveal any significant influence. CONCLUSION Patients with muscle-invasive clinical tumour stages and downstaging in cystectomy specimens represent a subgroup with significantly enhanced CSS rates. Further trials that integrate the parameters tumour size, stages cT2a vs cT2b and focality are required in order to define the independent prognostic signature of downstaging of tumour stages more precisely.

Abstract
An inflammation of the corpus cavernosum is relatively rare and must be differentiated from a tumour, abscess, thrombosis or embolism of the penile vessels. Most frequently inflammation of the corpus cavernosum is caused by iatrogenic interventions, followed by general infections and acute occlusion of penile vessels. Diabetes mellitus seems to be a predisposing factor. In the case of a 51-year-old diabetic patient with painful induration of the penis, an MR imaging study was undertaken to identify an inflammation of the corpora by exclusion of abscess formation. The inflammation responded well to a two-week oral Fluorchinolon treatment. Due to its high soft-tissue contrast, multiplanar layer images and, the MR scan was performed to identify an inflammation of the corpora cavernosa and to exclude an abscess formation. We consider a therapy with oral antibiotics to be sufficient for a non-abscess-forming cavernitis.

Abstract
Human actinomycosis is an infrequent chronic infection caused by gram-positive anaerobic bacteria with predominantly cervicofacial and intestinal manifestation. Retroperitoneal abscess formation displays a very rare localisation and is mostly incidentally diagnosed by histological examination. We report on a 44-year-old woman with left-sided flank pain and retroperitoneal abscess formation diagnosed by CT scan. Case history revealed preceding nephroureterectomy of the left kidney due to loss of kidney function and recurrent ureteral-vaginal fistulas. After CT scan-guided puncture and negative bacterial culture, actinomycosis could only be diagnosed by histopathological examination. Subsequently, besides abscess drainage calculated antibiotic therapeutic regimen was initiated. During the follow-up of 9 months there was no local or systemic recurrence. In the present case report, aetiology, clinical symptoms as well as diagnostic and therapeutic consequences are discussed.

Abstract
The diagnosis of primary retroperitoneal cystic tumors is very infrequent in surgical pathology. We report the case of a 51-year-old woman presenting with an incidental left-sided retroperitoneal mass (32 x 24 mm in diameter) suspected of being an adrenal tumor. Intraoperatively the tumor was identified as a cystic lesion filled with mucous secretion and laparoscopically completely resected. The diagnosis was histopathologically confirmed as a bronchogenic cyst. In this article the laparoscopic removal of such a rare benign congenital aberration resulting from an abnormal budding of the tracheobronchial tree is presented.

Abstract
BACKGROUND Due to an insufficient mean agreement between the Gleason score (GS) revealed from multibiopsy and definitive histology after radical prostatectomy (RP) of merely about 45 %, a modification of the GS including an elimination of GS 2-4 was -accomplished in 2005. The aim of the present study was to evaluate the concordance of GS and WHO grading in biopsy and definitive histology and to -determine parameters influencing the diagnostic accuracy of the biopsy and the prognosis. MATERIALS AND METHODS Within a 10-year-period before modification of the GS, radical prostatectomy was performed in 856 patients (study group, SG; mean age 64.2 years). The grade of agreement between GS and WHO grading in biopsy and definitive histology was calculated by kappa statistics (kappa) (for the complete and single time -periods). Furthermore, we assessed the univariable and multivariable influence of different preoperatively available parameters on disease-free survival (DFS). The mean follow-up period was 39 months (range: 10-139 months). RESULTS Undergrading of GS and WHO grading decreased continuously within the three time -periods in favour of a higher agreement regarding the histological results revealed from biopsy and definitive histology. However, we found only a poor to moderate agreement in the complete time period (kappa values of 0.354 for GS and 0.404 for WHO grading) that - with regard to both parameters - was improved by an increased number of biopsy cores taken. PSA value, clinical -tumour stage, number of positive cores (dichotomised at 34 %), annual RP case load (dichotomised at 75), and GS revealed an independent significant influence on DFS. Patients with GS 2-4 in the biopsy exhibited an upgrade to GS > or = 7 in only 5.7 %, and -showed, -independent of the definitive histology, a significantly better prognosis in comparison with patients presenting with a higher GS. CONCLUSIONS The results of the present study again suggest the independent prognostic impact of the GS revealed from biopsy. However, the concordance with the GS in the definitive histology remains deficient and is improvable by taking a higher number of biopsy cores. Although the elimination of GS 2-4 might be comprehensible for the pathologist's purpose, it results in a considerable loss of pretherapeutic prognostic information.

Abstract
To date, the current literature does not report on oncological surgery in bilateral renal cell cancer and coincidental simultaneous prostate cancer. We present the case of a 66-year-old patient presenting as a challenge due to this oncological-surgical constellation. Based on the present case study and the postoperative follow-up, we discuss possible surgical strategies and demonstrate that, even in the case of multiple tumour locations, a satisfying oncological and functional long-term result is achievable.

Abstract
PURPOSE Despite the development of new surgical techniques, the fascial sling procedure remains an important surgical technique for the treatment of female urinary stress incontinence. An advantage of combining it with an additional Burch colposuspension has been suggested. The objective of our study was to evaluate retrospectively selected patients who had undergone a fascial sling procedure with and without Burch colposuspension. MATERIALS AND METHODS Of a total of 390 females who underwent an incontinence operation at our department between 1990 and 1999, 56 patients had had a fascial sling plasty. A total of 50 patients (89 %) were followed for a median of 59.5 months. The median age was 60 years. 56 % of the patients displayed recurrent stress incontinence. The previous operations had been performed via a vaginal approach in 42.9 % and an abdominal approach in 57.1 %. The sling procedure used was that of Narik and Palmrich. Of the 50 patients, 14 had an additional Burch colposuspension. RESULTS The continence rates (no pads) were for patients with a fascial sling procedure alone 63.9 % and for the combination of both operations 64.4 %. An improvement (1-3 pads) was seen in 27.8 % and 21.4 %, respectively. No changes were seen in 5.6 % and 7.1 % and impairment was seen in 2.7 % and 7.1 %, respectively. After a five-year follow-up, the total patient satisfaction rate was 78 %. CONCLUSIONS The fascial sling is effective operative technique for treating female urinary stress incontinence, especially in severe and type III incontinence and in patients who had undergone previous operations for incontinence. The operation is safe and is the only technique that offers controlled overcorrection in desperate cases. An advantage of adding a Burch colposuspension to the fascial sling procedure was not detected in our patient group.
